Let Equals Equal Equals
Summary
Let Equals Equal Equals discusses the accessibility implications of the imperative API ariaDescribedByElements across shadow DOM boundaries. The post argues that the current behavior silently discards references when the target is in a different shadow root, breaking assistive technology relationships. It reviews historical context, proposals to fix the setter, consider nulling the getter, and emphasizes the Priority of Constituencies in the HTML design discussion, while also noting that even open vs closed shadow DOM should not prevent accessibility.
